In order to improve thermal conductivity, surfaces in contact (alumina, heatsink) should be coated with a silicone grease (type SI 340 from Rhône-Poulenc or Dow 340 from Dow Corning) or a thermal film (type Q Pad II) easier and faster to install than the grease. • The fastening of the resistor to the heatsink is under pressure control of two screws tightened at 2 Nm for full power availability. Tightening Torque on Heatsink LPS 300 2 Nm • The following accessories are supplied with each product: 2 screws CHC M4 x 25 class 8.8 and 2 M4 contact lock washers for heatsink mounting, 2 screws TH M4 x 6/6 and 2 M4 contact lock washers for connections. CHOICE OF THE HEATSINK The user must choose the heatsink according to the working conditions of the component (power, room temperature). Maximum working temperature must not exceed 155 °C. The dissipated power is simply calculated by the following ratio: ΔT P = --------------------------------------------------------[ R TH (j - c) + R TH (c - a) ] P: ΔT: RTH (j - c): RTH (c - a): Expressed in W Difference between maximum working temperature and room temperature Thermal resistance value measured between resistive layer and outer side of the resistor. It is the thermal resistance of the component: (see specifications environmental paragraph). Thermal resistance value measured between outer side of the resistor and room temperature. It is the thermal resistance of the thermal interface, the heatsink (type, shape) and the quality of the fastening device. Example: RTH (c - a) for LPS 600 power dissipation 180 W at + 50 °C room temperature. ΔT ≤ 155 °C - 50 °C = 105 °C ΔT 105 RTH (j - c) + RTH (c - a) = ------- = --------- = 0.58 °C/W P 180 RTH (j - c) = 0.112 °C/W RTH (c - a) = 0.58 °C/W - 0.112 °C/W = 0.468 °C/W Document Number: 50053 Revision: 27-Oct-10 For technical questions, contact: sfer@vishay.com www.vishay.com 65 LPS 600 Vishay Sfernice OVERLOADS In any case the applied voltage must be lower than UL = 5000 V. Short time overload: 2 x Pr/10 s Accidental overload: The values indicated on the following graph are applicable to resistors in air or mounted onto a heatsink. Power Resistor for Mounting onto a Heatsink Thick Film Technology POWER RATING The temperature of the case should be maintained within the limits specified in the following figure. To optimize the thermal conduction, contacting surfaces should be coated with silicone grease or thermal film, and heatsink mounting screws tightened to 2 Nm.
